In Port Canaan, Oregon, Jude Ellis has just become Sheriff after relocating to the small fishing town to leave the big city behind. But his plans of a quiet life are disrupted when 47 refugees from a war-torn country wash up on his beach seeking asylum. The thing is, they're actually from America and the war they're running from is 180 years in the future.
As the Department of Homeland Security seeks to make sense of the mysterious migration, Jude launches his own investigation with the help of his loyal Sheriff's Deputy. It also becomes clear that some of the Feds seem to know more about what's happening than they are letting on.
One thing becomes certain as the mystery deepens, and it is that both the townspeople's lives, and the lives of the newcomers, will never be the same.
Quite a few past shows with mysterious premises that started out well, then lost steam (and viewers) when they dragged out the mystery too long without some revelations to satisfy the audience.
Hope this one can buck that trend. It seems to have a decent cast.
